1 Claim. (01. 154-9) An object of my invention is to provide a tire of an arcuate head with a supporting post of easing holder of simple, durable and inexpensive the holder. construction. On the accompanying drawing I have used A further object i to provide a holder espethe reference numeral Ill to indicate a base for cially adapted for holding a tire casing while y t C s h e e e 8 P e e y grooving the treads thereof, as I have experof sufficient weight a d te o m y ienced considerable difiiculty in holding the casp e pp over of the t re holder.

A Figure 4 is an enlarged sectional view on the reflector 48 is preferably provided for the light line 44 of Figure 3 showing a clamp; and 46. The light is supported by a bracket 50 which Figure 5 is an enlarged sectional view on the in turn supports a rigid conduit 52 and a flexible 55 line 55 of Figure 2- showing the connection conduit 54. The conduit 54 permits variable position of the light 46 relative to the tire casing when positioned on the head 26.

Practical operation In the operation of my device, a tire casing is manipulated to receive the head 26, whereupon the operator may proceed with tread grooving or other operations on the casing. As the work progresses, the casing can be readily shifted along the head 26 to new positions as desired. The clamp screw l8 can be loosened for permitting raising of the extension post M to the full line position shown in Figure 2 when it is desired to stand up during the operations. Some operations, especially tread grooving, are quite tedious and at least part of the time it is desirable to perform the operations while sitting down.

The clamp screw 36 can, therefore, be loosened so that the seat can swing from the full line position of Figure 2 to the dotted position, the supporting leg 42 then supporting the weight of the operator instead of the seat arm 34 having to be made strong enough for this purpose. The seat can be rotated around the post l2 to the desired position for the convenience of the operator. The light 46, of course, can be adjusted to obtain best illumination on the work being done.

A few tools, such as a file 56 and a pair of pliers 58, may be supported by a tool holder 66 mounted on the conduit 52 where they are handy to the operator, for sharpening and adjusting his grooving tools.

The light 46 may be provided with the usual supply cord 62 terminating in a connection plug 64 which can be conveniently plugged into any available Wall socket.

It will be apparent that my tire casing holder is comparatively light and relatively compact. It can, therefore, be readily transported in a service truck or the like from one job to another.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

' I claim as my invention:

- In a tire casing holder, a base, an upright tubular post extending therefrom, an extension post having a straight portion mounted rotatably and slidably in the tubular post, a midportion extending angularly outward from the straight portion and an upright portion carried at the end of the midportion in a position at the edge of said base to permit a workman to stand close thereto; and operable as a handle to swing the extension post rotatably about the axis of said straight portion, and an arcuate head on said upright portion for mounting a tire casing, com-- mon means for clamping said straight portion at any desired rotative or elevated position relative to the tubular post, said clamping means comprising a band integrally coupled with the tubular post, said band and said post having 00- incident slots, one a single slot in said band and the other a single slot in said tubular post and a pair of ears at opposite sides of the slot in the band provided with an adjusting screw to tighten the band and tubular post jointly against the straight portion of the extensionpost.
